Where should I start? A guide to the levels

When you open a subject, you see a list of levels. It is easy to wonder: which one is mine?

Here is a simple way to choose.

The five levels

A short rule

• If a subject is new to you, start one level lower than you think. A quick, easy chapter costs you ten minutes. A chapter that is too hard costs you your confidence.
• If you are revising, start at your own level, and use the mock tests to find your weak spots.
• If you are just curious, choose General. The General level has the same clear lessons as High School (9–10), because good explanations do not need a syllabus.

Level checks for Python

Python has two level checks: short tests of 10 and 14 questions. If you already know some Python, take the Foundations level check first. A chapter in which you answer both questions correctly is a chapter you can skip. If you are new, take it anyway: it shows what you will learn.

Use the filters

Every list on the site, such as Problems, Quizzes and Mock Tests, has a Level filter. Choose a subject and a level, and the list shows only what exists there. If a choice is missing, it means that we have not written that part yet, and it is coming.

An honest note

We are building the site one chapter at a time. Today the most content is at High School (9–10), and Python and Statistics start from zero and suit every level. Some subjects have fewer chapters at other levels so far. If you cannot find what you need, tell us on the Contact page. You can also write your comments below. What learners ask for decides what we write next.
